Script to set DateTimeOriginal exif recursively

setExif.sh

# This script would set all pics to the same date, but ensures
# that each pic has a different hour and minute. This is useful
# to ensure locality of files when librarian/organize generates
# file names from their exif datetime.
let h=8
let m=0
find . -type f -name "*.JPG" | while read -r path
do
	let m+=1
	if [ $m -ge 60 ]; then
		let m=0
		let h+=1
	fi
	echo "$path => $h:$m"
	exiftool -DateTimeOriginal="2013:10:15 $h:$m:00" "$path"
